Farmall Cub Relay Help

Tash329 · Oct 15, 2009

I'm searching for a relay for my 1948 Cub and can't seem to find the right one. The one off my Cub has three terminals 2 on one side one on the other and mounts on the generator, Delco-Remy part #1116766. Anyone have an ideas where I might find one?

If your cub has a 4 position light switch Low High Dim Bright. and it is not using one of the terminals of the "cutout relay". I would gut the relay box and put a power diode in the space inside of it. A 20 amp diode out of a junk alternator (stripped out of the diode pack) will work fine. The diode does exactly what the relay did, but will last forever, and look very stock/original. It must be attached so it is not grounded, and the conduction direction is from Gen to amp gauge, not the other way. (many do not have markings, so testing the flow to ground with a test light from the negative battery post (assumes Positive ground) through the diode will not light the light. This assures the correct connection allowing charging current to the battery, but no flow from battery to gen. Jimn

They're pretty generally available. CaseIH, OEM and others. I haven't given a plug to Agri-Services in a while, wiringharnesses.com Excellent folks with an excellent product that I'd recommend to anybody.
